NEEDLE AND NEEDLE HOLDER.

Application filed March 12, 1921. Serial No. 451,727.

To all whom it may concern:

Be it known that I, EUGENE WERNER, a citizen of the United States of America, residing at Highland Park, in the county of WVayne and State of Michigan, have 1nvented certain new and useful Improvements in Needles and Needle Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a needle and needle holder for phonographs, graphephones and other record reproducing machines, and my invention aims to provide a needle that may be continuously used and adjusted when worn, the adjustment of the needle permitting of the tones emitted by the machine being regulated without removin the needle from its holder.

y invention further aims to provide a record reproducing needle that may be posltively held relative to a record and with the needle of considerable length it obviates the necessity of repeatedly changing needles, as is now the common practice in connection with talking machines or instruments.

My invention further aims to provide a needle holder and needle applicable to various types of talking machines, and the construction entering into the holder will be hereinafter described and then claimed.

Reference will now be had to the drawing, wherein- Figure 1 is a longitudinal sectional view 'of the holder with a needle therein, and

Fig. 2 is a cross sectional view of the same.

The holder comprises a sleeve 1 having its outer end provided with a tapering seat 40 2 for the tapered outer end 3 of a stem 4, said stem being mounted in the sleeve 1 and secured therein by solder or other fastening means, so that the sleeve 1 and the stem 4 form a unitary structure which may be placed in engagement with the tone arm of a talking machine.

The tapering outer end 3 of the stem 4 protrudes from the tapered seat 2 of the sleeve 1, and a side wall of the stem 4 is cut away, from the outer end of said stem to a point behind the sleeve 1, toprovide a jaw seat 5 having a central longitudinal semi-cylindrical groove 6 extending from one end of the seat to the other end thereof.

The jaw seat 5 may be of a width corresponding to the diameter to the stem 4- and it is preferable, irrespective of the width of the seat 5, to have the groove 6 axially of the stem t so that said groove may receive a needle 7, in the form of a piece of wire, for no instance seventy-five thousandths of an inch in diameter. To hold the wire 7 in engagement with said stem 4, a jaw 8 is placed on the seat 5 or between said seat and the walls of the sleeve 1, and said sleeve has a convene5 tional form of set screw 9 for clamping the jaw 8 against the needle 7 or the seat 5. That face of the jaw 8 confronting the seat 5 has a longitudinal groove 10 which cooperates with the groove 6 of the stem 4: in receiving the needle 7, and the outer end of the jaw 8 is tapered to conform and finish off the outer tapered end 3 of the stem 4.

With the jaw 8 loose in the stem 4 and the sleeve 1, the needle 7 can be shifted longitudinally of the grooves 6 and 10 so that the lower end of the needle will protrude from the lower end of the stem and may be placed in engagement with a record. When the protruding end of the needle is so worn the needle can be shifted and with the wire forming the needle of considerable length, it is obvious that a single needle will last for some time.

The stem 4 and the jaw 8 are assembled prior to being secured in the sleeve 1, and then the lower tapered end of said sleeve will prevent the jaw 8 from becoming accidentally displaced when released by the set screw 9. The jaw 8 will always be in position to clamp the needle 7 after being properly adjusted in the stem 4.

One embodiment of my invention has been illustrated, but I do not care to confine myself to the precise construction and arrange- 95 ment of parts shown other than defined by the appended claim.

What I claim is A needle holder comprising a sleeve having a tapered seat, a stem fixed in said 100 sleeve, said stem having a portion thereof removed to aflord a jaw loosely held by said sleeve, the jaw of said stem having one end thereof engaging said stem and the opposite end thereof engaging the seat of said sleeve so that said jaw cannot shift longitudinally of said stem, said stem and the loosely held jaw thereof having their confronting faces grooved and adapted for holding a piece of Wire or needle having its outer end co-axial of said stem, and a screw carried by said sleeve engaging the jaw of said stem and adapted to cause the stem jaw to clamp the Wire or needle against said stem. 1

In testimony whereof I affix my signature in presence of two Witnesses.
